## Abstract

A low-complexity all-analog circuit is proposed to perform efficiently Analog Joint Source Channel Coding (AJSCC), which can compress two or more sensor signals into one with controlled distortion while also being robust against wireless channel impairments. The idea is to realize the rectangular-type AJSCC using Voltage Controlled Voltage Sources (VCVS). The proposal is verified by Spice simulations as well as breadboard and Printed Circuit Board (PCB) implementations. Results indicate that the design is feasible for low-complexity systems like persistent wireless sensor networks requiring low circuit power.
